Anybody have luck with two regals? I have 2 small ones about 1.5 inch each. One is in QT, the other is established in the 300.
Yes, twice so far.
This is my current Sumatra Regal pair in my 100 gallon tank:

The female is about 85 mm in length (TL) and just loosing the last remnants of her eye spot.
The male's TL is about 95 mm. Both are still quite a bit away from maturity.
In the past I had a larger pair of Pacific regals that lived together for several years in a 750 liter (200 gal) tank.
Though it likely won't work if both are the same size.
I also don't know if it will work if both are still juveniles. I feel the larger one should at least be well into the transition from juvenile to adult.
Also, unless you have a several thousand gallon tank, they can't be of near identical size or one will kill the other.
I found that there should be at a minimum a 10% length difference.
The smaller one must go into the tank first and get at least a few hours time to get familiar with the new surroundings.
With fully mature specimen it is easy to tell males from females as the males have huge gill thorns. Though I never got to try if you can make a pair with a fully mature male and female.
